Banana overnight oats are a delicious, fast, nutritious and filling breakfast. These low calorie overnight oats are vegan, dairy-free and great for weight loss. Fresh bananas are cheap, sweet and perfect with the creamy oats.
Convenient and easy, overnight oats are great for busy weekday mornings, camping, road trips, traveling or anywhere where you can't cook.
These banana overnight oats use our vegan basic overnight oats recipe as the base!
🧄 Ingredient notes
- Banana - fresh bananas are sweet, full of fiber and low in calories. They are delicious and healthy topping or mix-in for overnight oats. Use a ripe but firm banana.
- Old-fashioned rolled oats - do not use quick oats for this recipe, they turn out mushy. Don't use steel cut, they don't get soft enough to enjoy with this method. You want old-fashioned rolled oatmeal for this method of cooking oats.
- Plant-based milk - any vegan milk you enjoy should work here, like almond milk (pictured), soy milk, oat milk (for that double oat flavor!), coconut milk, cashew milk and rice milk. You can use unsweetened or sweetened original varieties, if you like. Vanilla milk works great, too. If using a sweetened milk, you may want to reduce or omit the added sweetener.
- Maple syrup - adds a slight maple flavor, along with unrefined sweetness. Adjust the amount of maple syrup up or down, based on your preferred sweetness. Omit, if you desire.
- Ground flax - adds health benefits of added fiber, along with omega-3. Flaxseed also thickens the oatmeal slightly.
- Plant-based yogurt - amps up the creaminess and protein. I used Forager unsweetened vanilla cashew yogurt here. Vegan yogurts made from cashew, soy, coconut, almond and oat will all work here. If using a sweetened yogurt, you may want to reduce or even omit the added maple syrup.
📋 Substitutions and variations
Here are some suitable substitution options for the ingredients:
- Banana - you can use frozen banana instead of fresh, but fresh is much nicer (if using frozen, add them the night before, so they can thaw overnight).
- Plant-based milk - Use any plant-based milk you enjoy. Vanilla-flavored milk works especially well in this recipe.
- Maple syrup - use another sweetener like sugar, brown sugar, date syrup, agave nectar or coconut sugar instead. Or, omit the added sweetener altogether.
- Flax - use chia seeds instead of ground flaxseed. Or, omit them (it will be less thick if you omit one of these options).
- Nut-free - make this nut-free by using a nut-free plant milk, such as soy milk, rice milk or oat milk.
- WFPBNO - make this whole food plant based no oil by using plant-based milk and yogurt with no added oil or refined sugar.
- SOS-free - make this salt-, sugar- and oil-free by using a plant-based milk and yogurt with no added salt, sugar or oil. Omit the maple syrup, if desired.
Here are some variation ideas for these banana overnight oats:
- Blueberry Banana - add blueberries with the banana
- Bananas and Cream - top with extra vanilla yogurt for your cream layer
- Banana Cinnamon - add ½ teaspoon of ground cinnamon
